Amylyn,
it will be hard for a long time, but please remember that forever and always you are his little girl, and he wants peace and joy for you on this earth. When you can bear it (and it may be awhile) get out your photos from long ago, and remember the good times. Your love for him now is a testament to the sort of parent that he was.
